DIE AND CUTTER.

Application filed October 17,1924. Serial No. 744,185.

To all whom it may concern:

Be it known that I, Mauro TANZI, a subject of the King of Italy,residing in the borough of Brooklyn, county of Kings, city and State ofNew York, have invented an Improvement in Dies and Cutters, of which thefollowing is a specification.

This invention relates to dies for manufacturing tubular products andmore particularly dies which co -operate withcutters for cutting thetubular products in prede-- termined lengths. i

It is an object of the invention to provide a labor saving constructionfor cutting on diagonal lines tubular products such as macaroni, as thesame emerge out of the press. a

It is another object of the invention to provide a simple but effectiveconstruction for producing in one operation tubular products out ondiagonal lines.

It is a further object of the invention to provide a macaroni die andcutter, which is simple in construction durable and adaptable to be usedin connection with the ordinary macaroni press, and which permits themacaroni as it is molded tobe cut on diagonal lines as they areformedandcome out of the die, without further manipulation or additionalmachines.

Other and further objects of the invention, together with its advantagesand distinguishing features, will appear as the specification proceeds,which specification is descriptive of one embodiment of the invention asillustrated in the accompanying drawings, forming'a part of thespecification. It is understood that the said drawings only illustrateone example of my invention, that the specification is only descriptiveof such an example as illustrated, and that I do not limit myself to theexact features illustrated, for it is manifest that the same can beeasily altered, varied, and changed without in the least departing fromthe spirit of myv invention.

Referring to said drawings:

Figure 2 is a plan view of the aforesaid embodiment looking upwardly tothe illustration shown in Figure 1;

Figure 3 is a view of a broken-off portion of the base die hereafter tobe described and showing the outer face thereof;

Figure 6 is a cross sectional view of a portion of the die taken on line66 in Fig; ure 2;

' Figure 7 is a side view of the pin which co-operates with the die inthe formation of the tubular article, and hereinafter more F'gureS is aside view of the molded-and cut article produced by the die forming thesubject matter of this invention.

The article which is produced bythis device is known in the macaroniindustry as maltagliato, and is rather a demanded article, for it has,aside from its quaint appearance, certain other characteristics betterknown in the macaroni industry, which add to the tenacity of the articleafter it is cooked. V

Referring again to the aforesaid illustration 10 represents the lowerendof the cylinder of a macaroni press, which may be conveniently formedwith a flange 11 extending inwardly and right angles to the walls of thecylinder.

On this flange 11 is accommodated, or set, the die 15 which is formed,as more clearly shown in Figure 5, with a shoulder 16. The constructionheretofore described is old in the art, and no claim of novelty is madethereto.

The die 15 comprises a base die 17 and a cap member 18, the cap member18 being substantially at secured to the base die 17 by means of bolts 719 passing through alined holes in the cap member and in the base die.The base die 17 is formed with a series of concentrically arranged holes20 in which are arranged the cores 21, formed with prongs 22, throughmedium of which they are held in the holes, and with the shanks 23. Theholes 20 are contracted, or made smaller in diameter, at 25 where thecollar 26, on the shank 23 is located. The paste which. is presseddownwardlyv in the cylinder" is forced between the collar 26 and thewalls 27 at the restricted portion 25 and it through which extend theshanks 23 of the cores 21. This cap member 18 is formed with a pluralityof concentrically arranged inclined faces 35, to whichextend the holes30. There being as many inclined faces as 7 there are series ofconcentric holes 30; In the illustrated example there appearing only 2inclined faces, for th ere are 2' series ofholes 20and 30. The col'la26, as it will be noted from the illustration in Figure 5 and in Figure6, has a tapered portion 36 and a straight portion 37. The width of thestraight portion 37 is substantially shorter than the length of thewalls 27 of the contracted portion of the hole 20: By actual tests andexperiments it has been found, that unless the lower edge 38 of thestraight portion 37 extends to a distance shorter than the plane or theinner face 39 of the base die 17, the molded paste emerging from thehole 2O will clog and spoil the smoothness of the faces thereof. Specialstress is laid on this course by the pin 40, and thus prevented frombulging or warping. v

From theheretofore description it is seen that the die of this inventioncomprises substantially a base die 17 and a cap member 18, the two beingheld together by means of the bolts 19, and both being formed withalined holes, through which extend the plugs 21, with the shanksextending to a plane coinciding with the inclined faces 35 of the capmember 18. It is understood that these two members 17 and 18 could bemanufactured in one piece, and with any number of inclined faces 35, anda-ny number of holes 20 and 30'. The die is made in two pieces in orderto simplify its construction.

In order to effectthe cutting of the molded tubular paste thehereinafter described device is resorted to. Beforedescribing thisdevice it is necessary to briefly state that there are now inuse'macaroni presses that I have revolving knives for cutting the moldedtubular past at right angles to its axis as it comes out of the die.Such devices generally comprise a shaft 50, which by means of gears orpulleys is made to revolve below the cylinder ofthe press with its axissubstantially in line with that of the cylinder. To this shaft isconnected or coupled a knife which revolves with the shaft and whichcuts at the outer face ofithe: die

th material molded as it emerges. An object of this invention is that ofemploying as far as possible the standard equipment now in existence,and for that reason the hereinafter described apparatus is employed inconnection with the said shaft 50.

The cap member 18 is provided with a central hole 51 inwhich is madetofit the end 52 of a sleeve 53. This sleev 53 is conveniently contractedat 55 and threaded at 54. The contracted portion 55 is surrounded by arevolving sleeve 56 and is held in its place by means of a threaded ring60 which cooperates with the threads on sleeve 53. In order to eliminateas much friction as possible, an d'also in order to prevent looseness ofthe sleeve 56, l interpose between the revolving sleeve 56 and thethreaded ring 60 a bearin ring 61, which may be conveniently made ofmetal or of some other substance better fitted for the purpose used. Theremaining portion of the shaft 50 is enveloped by a tube which isprovided at its lower end with a gear or a pulley for receiving itsrotation movement.

In this case the shaftis held stationary and the tube 65 is made torotate about the shaft. However, the shaft may be made to rotate ifnecessary. The means that rotate the sleeve 65 are not shown, forthey'do not form a part of this invention.

On the sleeve 65:1 clamp, by means of a bolt 66 a clutch ring 67 whichis preferably provided with an arm 68 having a hole 69. The arm 57 ofthe revolving sleeve 56 is provided with a clutch pin '20 which iseither made to bear against one of the faces of the arm 68, or insertedin the hole 69. From this connection it is seen that the revolvingmovement of the tube 65 is transferred to th sleeve 56 which rotates onthe sleeve 53, the sleeve 53 and the shaft 50 being held stationary, andemployed as supporting mem bers for the revolving sleeve 56 and the tube65. v

The arms 57 and 58 are provided with openings adjacent their outer endsin which are insert-ed the shanks of the knives or cutters and 76. Thesaid shanks are firmly held in place by means of bolts 77, each. ofwhich is threaded in a hole in the arms 57 and 58 respectively,substantially at right angles to the axes of the shanks '55 and 776 andagainst which they bear when tightened. 1n the illustrated example theknif at the end of the shank 75 co-operates with' the outer inclinedface 35 of the cap member 18 and the knife at the end of shank 76cooperates with the inner inclined faee 35 of the said cap member. Incase there are. more inclined faces than the number" shown in theillustrated example then the sleeve 56 is provided. with as many armsas" there are inclined faces, each arm carrying a knife.

Reference is now had more specifically to .the invention, as defined in'Figure 3 wherein the knives or cutters 78 and 7 9 are illustrated asthey appear looking toward the die. It will be noted that the blades ofthe cutters are disposed in a position in advance or forward'of the axesof the shanks and 76. This is done so as to effect the cutting of themolded article as it emerges from the die in a plane for ward of theaxes of the shanks 75 and F6, for otherwise the point 80, for instance,of the shank 7 5' would interfere with the molded article before it wascut, if the knife was not arranged as described. The rotation of theknives is in the direction shown by the arrow A. The knives or cuttersare curved adjacent their outer ends 81 so-as to begin the cutting ofthe article from a point slightly rearward of a line drawn between thecenter of the die and thecenter of the pin 40. This is done so as toprevent acrushing of the ends of the article to be cut, and to preventany roughness that would take place at the lower portion of the cut endof the article produced.

The cutters in revolving about the inclined faces 35 of the die, cutthemolded article as it comes out of the die, in lengths determined bythe speed with which the article comes out of the die, and the speed ofthe knives or cutters. about the inclined faces. By changing either thespeed of the knives or cutters, or the speed of the molded article incoming out of the die, the lengths of the maltagliato are varied.

This device will therefore eliminate the necessity of a cutting machineor of transferring from the press the molded article to such cuttingmachine. All that is necessary is a tray below the die and the. cutterin ,which drops the article as it is severed from the die.

I would state in conclusion that while the illustrated and describedexamples constitute a practical embodiment of my invent-ions I do; notlimit myself strictly to the exact details herein illustrated, 'since,manifested, the same can be considerably varied without departure fromthe spiritof the appended claims:
